As expansion of balconies at apartments has been legalized, the major function of the balconies as a thermal buffer zone is disappearing. This weakens the ability of window to insulate heat and multiplies surface condensation. Thus more and more residents require solutions to increasing surface condensation and aggravation in thermal comfort. This study intends to provide basic data by evaluating performance of triple layered Low-E windows, triple layered clear windows, double layered Low-E windows and double layered clear window used for expanded balconies and marketed within the country in terms of surface condensation and thermal environment through simulation. Results revealed that no surface condensation occurred at double layered Low-E windows and triple layered Low-E windows. Surface condensation took place at double layered clear windows and triple layered clear windows at a relative humidity of 60%. Thermal environment analysis suggested that double layered clear windows showed the most time falling into the range of comfort at $23^{\circ}C$. The figure were $22^{\circ}C$ for triple layered clear windows, $22^{\circ}C$ for double layered Low-E windows and $21^{\circ}C$ for triple layered Low-E windows.

The purpose of the study was to suggest a cycle wear top jersey improved in mobility. The study developed a new cycle wear with improvement in dissatisfaction factors by planning design, pattern and the functionality of fabric. Considering the amount of sweat and the necessities of compression part, the basic material, the additional compression material, and the mesh material were arranged differently according to areas. The assessment of the developed cycle wear was composed of wearing comfort evaluation by female cyclist, photo analysis and garment pressure evaluation. The developed cycle wear was evaluated and compared with the current cycle wear. As a result of wearing comfort evaluation, the developed cycle wear was evaluated as better than the existing ones in all part, particularly in the areas of reflection tape and materials, partial pressure, pocket size, and prevention of loss. Photo analysis was in agreement with the appearance evaluation of the participants. As a result of garment pressure evaluation, the front neck part was more comfortable and the upper arm, abdomen, and waist area showed higher pressure, so it partially supported the body. This study has significant meaning for developing a new cycle wear top, protecting the body and improving the exercise effect.

Protective clothing developed for rose flower farmers has been evaluated to improve the working conditions. The requirements of rose farmers were first identified to design protective clothing for farmers working with thorny plants. A fit test was conducted to assess the thermal comfort and protective function against thorn pricking to compare and evaluate the usability of developed experimental clothing with existing working clothes. Based on the survey results of rose farmers' requirements, protective clothing was designed in the form of an apron (which was the most preferred after gloves) with a pattern designed for the production of experimental clothing. For the developed protective clothing, the strap and buckle closure method was selected to open the back of the body as much as possible; in addition, sleeves were made in the attachable form of a half-sleeve to protect the arms from the thorns. The fit test of the developed protective clothing and existing working clothes revealed the temperature and humidity inside the developed protective clothing to be significantly different in the back compared to existing work clothes. In addition to thermal sensations, the subjective humidity sensations were statistically significant different in the developed protective clothing compared to existing work clothes. The subjective protective function for thorn pricking was also found to be satisfactory.

The purpose of this study was to identify the preferred materials and design characteristics of nursing home clothes in order to collect the basic data necessary for the elderly nursing home clothes. It was to utilize the elderly nursing home clothes considering elderly body shape, hand function, illness. This study was conducted by questionnaire method and SPSS ver. 20.0 program was used. The preference for nursing home clothes material was high for cotton, and it was found that they prefer soft, stretch material, warm feeling material, and lightweight material. In the hygienic aspect, they favored sweat-absorbent materials, and preferred laundry- care-resistant materials with poor wrinkles and dirtiness. The nursing home clothes preferred a two piece form consisting of a round neckline, two pockets on both sides, a waistband of rubber band, long lengths, and a waistline pants. The most important function in the nursing home clothes was recognized as wearing comfort. Aesthetics, symbolism, color and print pattern were recognized as not important functions. Therefore, it is necessary to focus on the functional part such as wearing comfort in the design of the nursing home clothes. The material is also hygienic and comfortable to wear. In the case of the elderly, it is necessary to provide convenience for the wear of clothes through the development of stretchable material and detachment device since the movement range of muscles, arms, and legs is reduced. Based on this study, we will utilize it for the development of nursing home suit considering the characteristics of elderly person in the elderly society. It is to develop functional materials for the elderly in need of nursing home, to develop the pattern considering the elderly body shape, and to develop the desorption device considering the movement of the hand.

This study explored contemporary furniture theory and practice in Postmodernism mentioned as one of a kind furniture based on ideas from the tradition since Modernism. Qualitative conceptual analysis as the principal methodology was used to explore the postmodern furniture adopting or reflecting ornament from the tradition presented as postmodern furniture designers' point of view differently and variously. Thus, the examples about one of a kind or one-off furniture were dealt with Postmodern ideas appeared in the doubt over Modernism, Post-Modern furniture ideas from the traditional and Modern architecture, ornamental ism, Postmodern theorists, Postmodern furniture and the criteria. As a result, although one of a kind furniture design appealed newly from and based on the ornament of the tradition has been identified as new design like one of a kind furniture which shows lack of function, the piece with the meaningful ornament makes people happier in their daily life. Hence, one of a kind furniture, a work of art, has been required as striking a balance both function or comfort and aesthetics or beauty which makes the people more enjoyable.

The heavy equipment such as tracter has been studied to improve rather the performance of engine than comfort. The mufflers of tracters have various specifications according to their uses. The exact analysis of various mufflers is needed to reduce the level of exhaust moise, a major noise source of engine, to improve the ride quality of tracter. In this study, a software based on Green's function is developed to predict the performance of sound transmission loss for a muffler according to the locations of inlet/outlet pipes. The locations of inlet and outlet pipes can be fixed at different position individually. The conventional muffler has the locations of inlet/outlet pipes on the direction of longitudinal axes. On other hand, the inlet and outlet pipes may be located at the circumferential surface of a test muffler such as one of tracter. The software is verified by analysis and experiment on current muffler of tracter and the improvement technique is proposed to reduce the level of exhaust noise.

Track geometry changes by traffic loads. The bigger the changes are, the worse the riding comfort and running stability of train. This is so-called track irregularity and is the most important quality parameters of ballasted track. To objectively assess track irregularity, track geometry should be able to be measured. Practically, railway companies use moving chord method, which determine versine values via a chord. The versine is the vertical distance to curve measured in the middle of the chord. This type of method measures only versine of track irregularity curve by transfer function from the characteristics of measuring device. In this report, review the characteristics of two types of measuring tools by comparing the measurements. The one is GRP-1000 system, optical surveying system with Total station and lazar prism trolley. This calculates track geometry by surveying absolute coordinates of two points each on both rail heads. The other is EM-120, measures versine with 10m of symmetrical chord length.

In the present study the meaning of table in the Joseon dynasty period and also in the present age was researched, and its changing according to the times was searched as well. The results are as follows. First, the meaning of table in the Joseon dynasty period and in the present age has one thing, "laying something on table" in common from the functional aspect. Whereas the table in the Joseon dynasty period had the function of laying and keeping articles or decorations, that of the present age contributes to reading and doing office work of human beings and this exceeds the simple function to keep articles, because it touches parts of the human body, so it combines function of comfort accordingly, not only the function of storage. Second, it was differently presented from the aspect of shape. The table of the Joseon dynasty period strongly showed the shelf-like shape due to the set-up in layers, while the table of the modern times has the rectangle-like form in one layer. It has been transformed according to the functional changes. Third, it is different also from the constructive aspect. The table of the Joseon dynasty period had the construction with one panel on 4 legs in layer upon layer, but the table today has one upper panel on legs supporting it. Namely, the term "table" has been constantly used from the Josen dynasty period until today, but it has a totally different meaning according to the times on the basis of the changes in function and shape. In the furniture which maintains the function and shape of the square-typed table with 3 or 4 layers and the book table in the Joseon dynasty but is used under the different term in the present times it can be counted that display cupboard or bookshelf. Furthermore, desk and tea table can be regarded as furniture which exactly corresponds with the term "table" used in the present days, and also in the Joseon dynasty period there were furniture with such same function as like the writing table and small dining table.
